Chalk powder and water – Filtration is the method that can be used to separate chalk powder from water. Filtration involves passing a mixture through a filter medium that allows the liquid component to pass through while retaining the solid component.
Camphor and salt – Sublimation is the method that can be used to separate camphor from salt.
Sublimation is a process in which a solid directly changes into a gas without going though the liquid state. Camphor, being a volatile substance, can undergo sublimation under suitable conditions, leaving the non-volatile salt behind.
Sugar and water – Crystallization is the method that can be used to separate sugar from water. Crystallization involves evaporating the water from the mixture, causing the dissolved sugar molecules to come together and form crystals.
Fat and Cream – Centrifugation is the method that can be used to separate fat from cream. Centrifugation involves spinning the mixture at high speed, causing the denser component to separate and settle at the bottom of the container, while the lighter component remains on top.
